Subject: Handle Iop_NegF16, Iop_AbsF16 and Iop_SqrtF16 as non-trapping.
X-Git-Tag: VALGRIND_3_17_0~68
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d42a89fc9a4f90af07d93fe040c288b11f1d06ae;p=thirdparty%2Fvalgrind.git

Handle Iop_NegF16, Iop_AbsF16 and Iop_SqrtF16 as non-trapping.

Add Iop_NegF16, Iop_AbsF16 and Iop_SqrtF16 to VEX/priv/ir_defs.c
primopMightTrap. Also rewrite case statement slightly so GCC will warn
if an enumeration value is missed.
